MORTAR-HOD.

SPECIFICATION forming part of Letters Patent No. 456,504, dated July 21,1891.

Application filed November 18, 1 8 90- To all whom it may concern.-

Be it known that I, CONRAD CARLSON, a citizen of the United States, anda resident of Brooklyn, in the county of Kings and State of New York,have invented new and useful Improvements in Mortar-I-Iods, of which thefollowing is a specification.

My invention consists in the construction of hods for carrying mortarand bricks, the objects of which are to protect the open end frombattering up and splitting by the concussions to which it is subject indumping the contents; also, to prevent the sides from warping throughthe effects of the inside exposed to wet and the outside being dry;also, to prevent leaking through the bottom joint; also, to providebetter means of suspending them on the elevator-chains, and also toprovide strengthening-stays of the side bars of the handle-socket in anarrangement affording simple and ineffaceable distinguishing marks ofownership for protection against piracy, which is very common among theusers of hods, all as hereinafter fully described, reference being madeto the accompanying drawings, in Which- Figure 1 is a side elevation ofmy improved hod. Fig. 2 is an elevation of the open end. Fig. 3 is anelevation of the closed end. Fig. 4 is a side elevation of the hodhanging on the so-called ladder-chain elevator by the contrivance whichI provide for "the purpose. Fig.5 is a side elevation of said hod hungon the so-called hod-elevator chain of a different construction byanother contrivance which I also provide for such elevators. Fig. 6 isan elevation of part of the closed end, on an enlarged scale, toillustrate more fully the contrivance for preventing the joint of thetwo sides from leaking. Fig. 7 is a sectional elevation of part of theskeleton frame for protecting the sides from battering up and fromwarping, taken on line 00 a: of Fig. 2 and drawn to alarger scale. Fig.8 is a transverse section of part of said frame on line y 3 Fig. 7.

For the protection of the sides CL of the hod at its open end both frombattering and Warping I provide the V- shaped skeleton frame ofmalleable iron, consisting of two parallel side bars 0, located aboutthe thickness of the sides a, apart, or a little less, and

joined together at the ends and at suitable intervals along them by thecross-webs (Z, both the bars and the cross webs being wedge-shaped incrosssection, as shown in Figs. 7 and 8, and drive it onto said ends ofthe sides, forcing the webs (1 into the wood, and thus providesubstantial ironclad ends of great durability in resisting the shocks towhich the hods are exposed when said ends are let fall on themortar-board or the edge of a plank in discharging the 0011- tents. Thisframe is very rigid transversely and eifectuallyprevents the sides fromwarping by the effects of the wet mortar on the inside, while remainingdry outside. I construct it with the laterally-projecting angleears 7L,one on each side, flush with the lower end, and make the not-chi in thewood behind them, and thus provide for hooking the hod onto the rungs jof the ladder-chain kat two points sufficiently distant from each otherto prevent the hod from swinging sidewise and sometimes wrenching off,to which it is subject as commonly made, with only one hook at thecenter for so hooking on the rungs. I also construct it with otherlaterallyprojecting ears Z farther up the sides of the frame (Where pinshave commonly been fasttened to the sides a of the hod) for lodging inthe hook-links m of another form of elevatorchain, as or, frequentlyused. The advantages of this arrangement are the simpler method ofproviding these cars, which are cast together with the frame, and theyare more substantial, and I also construct said frame with an integralarm m, extending from each outside bar 0 backward and obliquely downwardalong and so as to have bearing contact with the sides 0 to a suitabledistance back of the end and near the lower edge to receive afastening-bolt 'y to prevent the frame from being thrust off by theshocks.

I make the joint 0 between the two sides a by beveling them so as tomeet in a vertical line and saw a kerf at right angles thereto in eachedge and insert a thin metal strip 19, extending from end to end, whichmakes awatertight j ointand prevents leaking onto the shoulder of thecarrier. At the rear end I apply an endless band of iron 3, extendingall around, including head .2, and insert the boltqto bind all the partstogether. The V frame secures said joint at the open end. It will beseen that with the ends of the two sides bound together by the frame andband, and the packing-strip fitted in the kerfs of the meeting edges thenailing of the edges is not required, for although the joint may openslightly by the effect of Wetting and drying it will not leakinconsequence of the packingstrip. By dispensing with the nails muchsplitting caused by them is avoided.

Besides packing the joint tight the metal strip p affords a materialprotection against a common practice amonghod-carriers of appropriatingto themselves the beds of hodelevating companies, which are longer thanthe hods that are to be carried up, and dis guising them by sawing themshort.

At the present timehods having a metallic socket to for the handle havethe plain branches 1; extending up the sides 0 without a cross-staybetween them, Which,though not a very essential requirement, is usefulfor greater strength; but besides the application of such a stay forgreater strength I. propose to utilize it also for a distinguishingowners mark by constructing it in the form of initial letters, as w, orany other distinctive mark, made integral nith the branches, so that itcannot be effaced without showing the mutilation incident to itsremoval,

The common practice of marking is by branding the sides; but .the brandscan be readily scraped out so as to leave no sign.

, I claim as my invention- 1. The combination, with the sides of amortar-bod, of the \l-shaped metallic re-enforcing and stiffening frameconsisting of side bars and integral cross-webs driven on the ends ofthe sides, substantially as described.

2. The combination, with the sides of a mortar-110d, of. the V-shapedmetallic re-enforcing and stiffening frame consisting of side bars andintegral cross-webs driven on the ends of the sides, and thelaterally-projecting integral arms of said frame for hooking on theelevating-chains, substantially as described.

3. The combination, with the sides of a mortar-110d, of the V-shapedmetallic re-cnforcing and stiffening frame consisting of side barsandintegral cross-webs driven on the ends of the sides, and thelaterally-projecting integral ears of the side frame, flush with thelower end of said frame, for hooking on the elevator-chain, said hodhaving the notch in the bottom behind said frame, substantially asdescribed.

4. The combination. with the sides of a mortar-bod, of the V-shapedmetallic re-enforcing and stiffening frame consisting of side bars andintegral cross-webs driven on the ends of the sides and therearWardly-extended arms along thesides a and bolted thereto,substantially as described.

5. The combination, with the sides a, having the beveled and kerfedmeeting lower edges, of the fiat metal packing-strip inserted in saidkerf, the V-frame fastening the sides together at the front end, and themetal band and bolt binding said sides and the head together at the rearend, all substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 31st day of October, 1890.

CONRAD CARLSON.
